This invention relates to actuating means for Siphon-discharge apparatus with vertically movable siphon bell for delivering different quantities of water at will (large and small flush).

Actuating means for Siphon-discharge apparatus with vertically movable Siphon bell are already known which admit of delivering different quantities of water at will (for large and small flushing) by pulling down the conventional opl() erating handle to different levels.

In accordance with the present invention there is employed for delivering one quantity of water (large ush) in the usual manner, the actuating means normally attached to the draw member 151 for lifting the siphon bell, and for delivering another quantity of water (small flush) a further actuating means which is likewise connected with the said draw member, and which is movably supported in a fixed housing which at the same 2Q time serves as a guide for the draw member. vIn order to preclude the possibility of mistaking the one actuating member for the other themanner of operating these two members is arranged to be different (e. g. in the one case by pulling and in 2,5. the other by pushing). To enable the lift of the siphon bell to be adjusted as required, and that independently for the large flush and for the small flush, parts of the actuating mechanism are made adjustable. Further features of the in- 3Q, ven'tion relate to constructive details.

The invention is illustrated, by way of example, in the accompanying drawing, in which:

Fig. 1 shows in section a flushing cistern equipped with Siphon-discharge apparatus fitted 3.5,; with actuating means according to the invention.

Figs. 2 and 3 show forms of` construction of actuating means according tothe invention, `in section, on an enlarged scale.

Referring to Fig. 1 of the drawing, the ilush- 4.02` ing installation consists of a water tank I, with an inlet or feed pipe 3 controlled by a float valve 2, and a discharge pipe 4 over which there is disposed a siphon bell 5 adapted to be lifted by means of a draw chain 5 and a fulcrumed lever 'I.

45u The siphon bell 5 is provided inside with an open section of tube 8 of which the lower end, provided with gasket elements 9, is seated in the manner of a valve upon the discharge pipe. The upper end I of the section of tube 8 is located 50. so high up in the siphon bell that it is above the highest level reached by the water in the tank.

The actuating means for lifting the Siphon bell consists of a rod I4 which is connected by means of the sleeve I2 and ring II to the draw 551; chain 6, and by means of the ring 22 to the handle A like 2I to the back plate 20 which is secured for example to a wall. In a slot in the rod I4 there engages the one arm of a bell-crank lever I9 5 which is pivoted at I8 in the housing I5, and of which the other arm is articulated to a stem extending out through the wall of the housing and tted with a knob I'I.

To effect the large flush the rod I4 is pulled 10 down in the usual manner by means of the handle `23 soas to lift the bell of the Siphon to such an extent that siphonic action is set up and the entire contents of the tank become discharged. To eect the small flush the knob I1 is pressed l5 towards the housing, with the result that the rod I4 is pulled down to a less extent than when operated by means of the handle. The bell 9 of the Siphon is then only slightly lifted, and water flows from the tank only as long as the knob is kept pressed in. When the knob or the handle is released the rod I4 returns to its position of rest in response to the action of the spring 24. By screwing the ring ll in the Sleeve I2 which is attached to the rod I4 by means of the screw I3 25 the draw chain may if desired or necessary be tightened up. The means provided for guiding the rod I4 also serve to guide the chain, and thus prevent the latter from becoming twisted.

' In the form of construction shown in Fig. 2 `30 the actuating knob I1 is of tubular shape and screwed on to a thrust stem 25 articulated tothe bell-crank lever I9. By rotation and consequent adjustment of this knob the angle of pivotal movement of the bell-crank lever I9 co-acting 35 with the rod I4, and therefor also of necessity the extent of the lift imparted to the Siphon bell for effecting the small flush, is readjusted. The actuating knob `I'I may be fixed in any desired position of adjustment by means of grub screws 40 26. These screws are suitably countersunk, as a precaution against unauthorized alteration of the lift of the siphon bell and consequently of the quantity of water discharged for the small flush. In order to provide for adjustment of the lift of the siphon bell for the large ilush also, the handle 23 is connected by means of the ring 22 to a sleeve 2'I guided in the casing I5, this sleeve being screwed on to the rod I4. The ilange 21 on this sleeve serves as an abutment for limiting the movement of the rod I4 when the latter is pulled down. The adjustment of the lift of the Siphon bell is effected by rotating the sleeve 21 which is then fixed in the desired position by means of countersunk set-screws 28. In order that the press-in knob may be used for actuating the Siphon-discharge apparatus for the delivery of the larger quantity of water, and the pull handle for the delivery of the smaller quantity of Water the rod I4 can be made to consist of two slidably interengaging or telescoped parts, namely a sleeve-like upper part I4a and a lower part I4b guided thereon; the lower part has a lateral aperture I 4c in which there engages a correspondingly shaped lug I4d on the sleeve I 4a. The lower part |417 is coupled to the upper part I4a in the direction of pulling, and is also locked against rotation. t is only on pulling down the handle 23 that the two parts I4a and I 4b of the rod I4 are rigidly connected together. The return movement of the draw rod I4 is effected or'assisted by the springs 24 and 29. When the pressing-in knob is being operated the part I 4a of the draw rod can also be moved on when the lower part I4b encounters a resistance or obstruction.

In the form of construction shown in Fig. 3 of the drawing there is` provided, instead of the push-in knob and bell-crank lever, a handle 30 which is connected to the rod I4 (portion Illa) and which is guided in a slot 3| in the housing I5. In order to provide for adjustment of the stroke of the projecting handle 30 there is screwed on to the rod I4 a sleeve 32 which is guided in the housing, and which in its turn is connected,

- through the intermediary of the ring II, to the draw member for the siphon bell.

The device according to the invention has the particular advantage that it can readily be operated by anyone, while the Siphon-discharge ap- .paratus is saved from undue or unnecessary strain, and the draw chain prevented from becoming twisted. Since the actuating device is separate from the ushing apparatus proper it may be fitted to existing flushing installations.
